Overview
Immunosuppressed patients, neonates, pregnant women and elderly patients have higher risk of contracting listeriosis. Immunosuppressed patients with listeriosis are also more likely to develop serious complications, such as life-threatening bacteremia and meningoencephalitis.[1]
Risk Factors
Pregnant Women
About one in seven (14%) cases of listeriosis occurs during pregnancy. Pregnant women are about 10 times more likely than the general population to be infected. Pregnant Hispanic women are about 24 times more likely than the general population to get listeriosis.[2]
Older Adults
More than half (58%) of Listeria infections occur among adults older than 65 years of age. Adults 65 years and older are about 4 times more likely than the general population to be infected.[2]
People with Weakened Immune Systems
Individuals within this group also have a higher risk for infection due to underlying medical conditions such as cancer and immunosuppresive therapy (i.e., steroids, chemotherapy, radiation), liver or kidney disease, diabetes, alcoholism, and HIV/AIDS. AIDS patients are almost 300 times more likely to get listeriosis than people with normal immune systems.
Newborn Babies
Newborn babies suffer the most serious effects of listeriosis in pregnancy.
